OHIO, A CORPORATION OF METALLIC PACKING.

SPECIFICATION forming part of Letters Patent No. 770,483, dated September 20, 1904.

Application filed July 8, 1904. Serial No. 215,698. (No model.)

To (LZZ whom zit may concern.-

Be it known that I, HAROLD P. TIPPETT, a citizen of the United States, residing at Oolumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Metallic Packings, of which the following is a specification.

Myinvention relates to a new and useful improvement in metallic packings. I

The object of the invention is to provide a packing in which certain difficulties heretofore encountered are overcome. In such packings where segments that interlock have been employed it has been found necessary to force said segments into their locking engagement around the rod, and when once they are locked together it is impossible to remove them without breaking the lips or entirely disengaging the segments from the rod. Packings of this nature wear more rapidly upon their sides than upon their inner or outer peripheries, and where interlocking lips are used the'packing soon wears so thin that the lips break off, which greatly decreases the efliiciency and life of the packing. Therefore the more essential purposes of my invention are to provide a packing that will obviate the above objection and one which is peculiarly shaped and formed so as to readily fit in place and present steamtight joints under all pressures.

Finally, the object of the invention is to provide a device of the character described that will be strong, durable, and eflicient and comparatively simple and inexpensive to make and one that will be operative throughout its life.

WVith the above and other objects in view the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the drawings, where- Figure 1 is a view in elevation of my packing-ring. Fig. 2 is a detailed elevation of one of the segments. Fig. 8 is an inner face View of the segment. Fig. 4: is a plan view of the ring, and Fig. 5 is a detailed end view of the tongue end of the segment.

In the drawings the numeral 1 designates the segments of which the ring is composed.

Ordinarily I employ three of these segments; but where packings of considerable diameter are employed more segments may be used. Each segment is formed with a tongue 2, having the angular end 3 and extending from the angular shoulder I. The tongue 2 has a width equal to half of that of the segment and extends from the diametrical center of the segment to the outer surface thereof. An inclined face 5, extending in the same plane with the shoulder 4, projects from the side of the tongue 2. The opposite end of the segment is formed with an L-shaped inclined face 6, which conforms and registers with the shoulder 4 and the inclined face 5 of the next adjacent segment when the same are assembled in the ring. An offset recess 7 is formed with an inclined wall 8, which extends at such an angle as to contact and register with the end 3 of the tongue 2 when the shoulder 4L and faces 5 and 6 are brought into contact. It is to be observed that the inclined face 6 and the tongue 2 extend in opposite directions from the diametrical center of the segment and that the recess 7 and inclined face 5 are disposed likewise. It will be readily seen that there are no thin projecting lips to wear and snap off and that the segments when once assembled are held against longitudinal displacement upon the rod. Each segment is formed with slightly-rounded sides 9, which curve inward from the inner periphery or bore 10 to the outer periphery 11, which is, as shown in the drawings, considerably narrower than the said inner periphery. The packing is especially designed to be used in connection with a suitable spring-rigging. It is to be observed that the tongue 2 is quite short and stubby, while the recess 7 is comparatively small, thus presenting an extremely strong and durable packing-segment. It is also to be observed that as most of the wear is taken up by the sides 9 the bottom wall 12 of the offset recess 7 practically maintains the same thickness as the said wearing action takes place, thus preserving its efficiency during the entire life of the packing. WVhen the segments are assembled about a rod, the engaging elements register, as hereinbefore described,

' ed to receive the tongue of the next adjacent segment When the segments are assembled.

2. Ametallic packing-ring composed of segments having the curved faces 9 and the inner periphery 10 of greater Width than the outer periphery 11, each segment having the tongue 2 provided With the inclined end 3 projecting from the inclined shoulder t, and the inclined face 5 extending in a plane parallel to the shoulder 4 Which lies at an angle to the end 3, and said segment being formed on its opposite end With the inclined L-shaped face 6 conforming to the angle of the plane of the inclined face 5 and shoulder 4E, and an offset recess 7 formed in the face 6 and provided With the inclined rear Wall 8 conforming to the angle of the end 3 of the tongue 2.
